The spte pointing to the children SP is dropped, so the whole gfn range
covered by the children SP should be flushed. Although, Hyper-V may
treat a 1-page flush the same if the address points to a huge page, it
still would be better to use the correct size of huge page.
Fixes: c3134ce240 ("KVM: Replace old tlb flush function with new one to flush a specified range.")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
